IMPROVEMENT IN BLIND-FASTENINGS, &C.

`Specification forming part of Letters Patent No. 37,597, dated February 3, 1863.

To all whom it may concern Be it known that we, WENZEL TOEPFER and HERMAN RUGEE, of Milwaukee, in the county of Milwaukee and State of Wisconsin,

V-have invented a new and useful improvement in blind-fastenings and in means for regulating or adjusting the slats of blinds 5 and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specication, in which j Figure lis a top or plan view of one of the butts and the fastening of a blind, together with a portion of the window-frame, thelatter being in section in order to show the working parts; Fig. 2, a detached perspective view of one of the butts for brick or stone buildings Fig. 3, aperspect-ive view of all the parts comprising the invention, a portion of the window-frame being broken away; Fig. 4, a horizontal section of Fig. 3, taken in the line a: Fig. 5, a detached perspective view of one ofthe butts for frame buildings 5 Fig. 6, a detached view of the parts pertaining to the slat-regulatin g device; Fig. 7, a vertical section of the face-plate, taken in the line y y, Fig. 3; Figs. 8 and 8b are detached perspective views of guard-plates.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to a new and useful arrangement of means for opening and closing window-blinds, and adjusting their slats opening and closing them) from the inner side of the window within the compartment, without the necessity of raising the sash.

To this end the invention consists in the employment or use of a sliding bar fitted in the window-frame and connected to the lower butt of the blind by a link, and using, in connection with said parts an arbor or shaft arranged in such a manner as to be turned, when the blind is closed, from a knob placed loosely on the sliding bar above mentioned, said arbor or shaft when turned acting upon a lever attached to the blind and connected with the slats thereof, as hereinafter fully shown and described.

To enable those skilled in the art to fully understand and construct our invention, we will proceed to describe it.

A represents a portion of a window-frame,

a being one of the side jambs thereof, and b the sill.

B is the blind attached to the jamb a by means of butts B, the construction of which is shown clearly in Figs. 2 and 5, the upper parts of the butts being provided with pendent pintles c, which fit in recesses d in the lower parts. lThis is shown clearly in Fig. 5. The upper part of the lower butt of the blind is provided with an arm, e, to which a link, C, is attached by a. pivot, f, said link being formed of two parts, gg, one directly over the other. The inner end of this link G is connected by a pivot, h, with a sliding bar, D, which is fitted Vin the jamb a in a guard-or guide, z'. (Shown separately in Fig. 8 and shown applied in Figs. l and 3.) The bar D also passes through a face-plate, F, secured to the inner side of the jamb a. The bar D is provided with a notch or recess, j, in its lower edge, and near its inner end, and upon said bar a rod, k, is made to press by means of a spiral spring, l. (See Fig. 3.) This pressure-rod 7c of course presses the bar D downward and causes the notch or recess j to catch on the lower edge of the opening ax in the faceplate F, through which the bar D passes, and by this means the bar D is prevented from casually moving, and the blind D retained in an open or closed state and fastened in either of the two positions named, so that it cannot be moved from the other side 0f the window. The blind, it will be seen, is opened and closed by moving the bar D forward and backward in the jamb a, the link G swinging either to the right or left, to force open or to close the blind. In the jamb a there is placed a rod or shaft, Gr, which is parallel with the bar D and at the short distance below it. This rod or shaft Gr has its inner bearing in the face-plate F and its opposite bearing in the ground, which is shown separately in Fig. 8a. The rod or shaft Gr is allowed to turn freely in its bearings, and at its outer end it is provided with an arm, H, which projects at right angles from it on the rod or shaft G. Near its inner end there is placed a lever, I, the outer end' of which is connected by a pivot, n, to a slide, J, which extends upward at the inner side of the faceplate F, and is provided at its upper end with a lip, o, which passes horizontally' through a vertical slot, p, in the face-plate. (See Figs.

1, 3, 4:, 6, and 7.) On the rod or shaft @there is also placed a spring, K, (shown in Figs. 3, 4, and 7,) and this spring has a tendency to keep the rod or shaft so turned that the arin H will be in a horizontal position, and the lip 0 at the upper end of the slotp in the face plate. L represents a knob, which is fitted loosely on the inner end of the bar G, and has a pin, q, projecting at right angles from its arbor i'. This pin q, when the knob L is turned in the proper direction, ccnies in contact withY the lip o ofthe slide J and Vforces down said slide, so the latter will, through the medium of ever I, turn the rod or shaft G and elevate the arm H, the latter assuming its original positionin consequence ofthe action of spring` K as soon as the knob L is released by the operator.

Y M represents the slats of the blinds, and N the rod, to which they are connected, as usual, by staples. The slat-rod N has a rod, connected to it by a pivot, s. This rod U extends downward and is connected at its lower end by a pivot, s', with a lever,P, which is secured by a fulcrurn-pin, u, to the lower rail, e, ofthe blind B. rlhe lever P has a pin, cxx, attached to it, against which a spring, Q, bears, said spring having a tendency to keep the outer 0r free end ofthe lever P depressed or forced down. When the blind B is in a closed state, the outer or free end ofthe lever l is directly over the arm H of the rod or shaft G, and it will be seen that by turning the knob L the slide J will be depressed in consequence ofthe pin q striking or coming in contact with the lip 0 of the slide J, and the latter, in being forced down,turns the rod or shaft G through the medium of the lever I, and, the arm H being thereby elevated, the outer or free end of the lever P will be iased and the slats opened. The slats are retained in an open state in consequence of the arm H, when elevated, being about at right angles against the lever P, as shown in Fig. 6. The slats may be closed at any time by simply pressing upward the lip o ofthe slide J by turning the knob L in a reverse direction. Thus the blind B may be opened and closed from the inner side of the window, or within the apart ment, without raising the sash and the slats M ot" the blind, when the latter is closed, may be also opened and closed without raising the sash.

Having thus described our invention, what we jointly claim as new, and desire to secure by Letters Patent, is

l. The sliding bar D, connected with the lower butt, B, of the blind through the medium of the link C.

2. Securing said bar D, or preventing the casual movement of the saine, and at the saine time locking the blind by means of the notch or reeessj, pressurerod k, and the opening in the face-plate F, as herein shown and described.

3. The rod or shaft G, provided at one end with the arm H and at the opposite end with the lever I, connected with the slide J, in combination with the pin q on the arbor nr of the knob L, the lips o, on the slide J, and the lever l? and rod 0 attached to the blind B, all arranged to operate as and for the purpose herein set forth.
